To (066 wit/mt it my concern.

. Be it known that I, JonN WILKINSON, of Syracuse, in the county of Onondaga and State of New York, have invented a certain new and useful Gearing, of which the following is a specification.

My invention has for its object the production of a. gearing which is especially applioable for transmitting power from the engines or other motors of automobiles to the propelling wheels thereof, and is particularly simple in construction,' economical in manufacture, and durable and efficient in use; and to this end it consists in the devices and combinations hereinafter set forth and claimed.

Figure 1 is a sectional View of apreferable embodiment of my gearing, portions of the driving member being broken away and indiouted by dotted lines and part of an engineframe being shown by dotted lines. and 3 are sectional views taken on lines 2 2 and 3 3, Fig. I. Fig. 4 is a sectional view taken'on line 4 4, Fig. 1. View of sportion of the case. i

a support E, planetary gears F G, mesnsfor' gear D and the limiting therotstion of'the support E, and means 1 port E to the driving ii The case A is here illustrated as consisting of a, main body a, which supports a movable section a. and is mounted on the frame A of the engine or other niotor for sctusting the driving member B. Said main body a consists olparts or divisions a a, removably secured together by suitable fastening means, as bolts, (not shown) which permit the part or division a to be removed from the part or r connecting the sup-' ember B.

as a crankshaft extended within the case A, 7 journaled in a part of the frame A (not illustrate'd) and in the hub a and provided with gears b it of unequal diameter and a support ti, detschably secured to said member B by ke s or other dBSlI'8.l)lB.ll'l6&1lS. Said gears 16 ll, which form essentially, parts of the drivinginember are provided with hubs of less diameter than their toothed surfaces, the gear 6 of larger size be' generally- .niounted on the hub of the ges li. The in- "her fees of the support 6 is engaged with the oontiguonsend feces of the hubs of the gears '5 6, and the outer face of said support is provided with a. hub closely fittingwwithin the r (mm of end with s spindle b and an engaging posits sides of the cam "firm is, arranged on 0 being formed of angu a, the engaging arm lar eross section.

The

The driving member B is here illustrated move aof the case A and "tion of the opening o notfoesulpied by the 'and formed integral with said teeth of the gear 1) thus project on opposite sides of the disk 0!.

As best seen in Fig. 1, the support E is rev oluble relatively to the driving and driven members, and its central portion is arranged at the outer side of the. support I). One side of the support I is provided with a flange e, projecting toward the contiguous side wall of the main body a of the case A and encircling the support and the other side of said support E is provided with a huh e, extending within the gear 1) and detachably mounted on the huh of the gear I), and with a series of spindles c also extending within the gear D, each of the spindles (2 being arranged eccentric to the axis of the support and formed integral with said support and being unsupported at corres mnding ends.

The planetary gears F (i are of unequal di ameter, are loosely mounted on the spindles c" e at opposite sides of the. disk of, are normally detachable from said spindles, and are respectively connected to the gears b b D, being here shown as directly in mesh with said gears b I) l). The opposing side faces of the gears F G are preferably engaged with opposite sides of the disk (1" in order that said disk may normally prevent the movement of these gears endwise from their supporting spindles c e.

The means for limiting the rotation of the ear I) and the support E consists of split riction-rings h h of similar construction, interposcd between contiguous surfaces of the case A and the partsD E and having contiguous ends prevented from movement rela tively to the case A by suitable means, as

, screws It, and their other ends provided with slots for receiving the heads of additional means, as screws h, and with slots for receiving the inner ends of rocking en aging means, as'levers h", which are adjusta le on the case A and clamp'the friction-bands h h upon the peripheriesof the gear D and the flange a. One of the levers b may be provided with a roller 71", enga ed by a cam h on the movable section a, and the other lever It may be actuated. by a link or other powertransmitting means (not illustrated) suit ably connected to said lever for rocking the same on its pivot.

As usually constructed the means for connecting the support E to the'driving member B consists of a split friction-ring i, arranged within the flange 6 and having its intermediate portion formed with a cut-out t for receiving the engaging arm I) and an expander i, loosely and detachablv mounted on the spindle b and having one end movable between the separated ends of the friction-ring ifor forcing said ends apart and engaging the ring '5 with the inner face of the flange eand having its other end engaged with the cam a"' and movable outwardly thereby when the movable section 0, is forced endw se.

In the operation of my gearing the section a is moved in one direction until the camways a force the ram (1. inwardly and moves the expander into its operative position, thus locking the supports h E together and compelling the driven member to rotate forwardly at the same speed as the driving member. \Vhcn it is desired to rotate the driven member forwardly at reduced speed, the movable section a is revcrsel v turned for forcing the cam a" into its inoperative position and causing the cam. h to actuate the corresponding lever h for clam ing the friction-band it upon the gear .0 ant holdingsaid gear stationary, whereupon the planetary gears 1* cot'iperate with the gears b D to efl'ect the desired rotation of the driven member. The reverse movement of the driven member C is effected by moving the section a of the case A on its axis until the cam 71 is with drawn from its operative engagement witli the corresponding lever 71* to permit the friction-band h to release the gear D and by ac-' tuating the other lever h to clamp the friction-band 72 upon the support E, thus holding said support stationary and compelling the gears b G to rotate the gear I) in a direc-.

tion opposite to that of the driving member,- which movement is transferred by the gears F b to the driven member C. As will be obvious to those skilled in the art, the arts of my gearing within the case A may all e readily detached from each other after the removal of the part or division :1 and consequently a gear broken or unduly worn may be readily replaced without removing rivets, pins, or other means.

The construction and operation of my gearing will now be readil understood upon reference to the foregoing escription and the accompanying drawings, and it will be apparent that more or less change may be made in the construction and arrangement of the component parts thereof without departing from the spirit of my invention Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
